“Shout joyfully to God, all the earth, alleluia, sing a psalm for his name, alleluia; give glory for his praise, alleluia, alleluia, alleluia.” (Ps 66(65):2)

For the first time in Easter season, we have a triumphant Sunday introit, a melodic span of an entire octave within the antiphon in the 8th mode that generally tends to be very clear and unambiguous. In many places (like omnis in the first line or gloriam laudi in the second and third lines) the medieval neumes order us to emphasize and lengthen the consonant m or the diphthong au. This is very common in Gregorian chant, but it give a paschal chant a quite lively and affirmative mood. The singers enjoy the sounds that they make with their vibrating lips. This technique is a bit strange to Germanic languages but in medieval Latin it was one of the most important strategies to make words joyful and meaningful.
